PetArmor Flea & Tick Spot Treatment for Dogs, 89-132 lbs
I use this and have no problem. I also spray my dog pen. He only goes out. About twice a day.
I have used Pet Armor on my four dogs for over 7 years and find it to be extremely effective. It works as well as Frontline for a fraction of the cost, since the active ingredient is the same in both products. Why pay more for the same product, just because your vet gets a kickback from Frontline in order to promote the product. Be smart, save money, and protect your precious dog.
I use this always and have good results! Good product for the price recommend it!
I put it on my dog a week and a half ago. He had only a few fleas he picked up from another dog. He still has fleas!
